3. Self-adaption system to stratum shortens handle regulating time of driller, improves drilling efficiency and ensures perpendicularity of the hole.

4. We design and use DTH hammer with interconvertible high-low frequency according to situation of single using DTH hammer (low frequency, big impacting energy) in prospecting drilling project nowadays. Choose high frequency matching parts of DTH hammer to improve drilling frequency when soft formation as fâ¤8.

5. New design of power swivel that circulation drilling fluid and bearing chamber are separate reduces damage probability of bearing.

1. This drilling rig uses the modular design, disassembling fast, convenient and reliable.It includes Dieselengine, console platform, the mast assy., the power swivel, the aerodynamic system, the drilling tool and other appendices.

3. Pull up & down of drilling tools is achieved by hydraulic motor driving roller chain.

4. The drilling rig equipped with safety and warning mark, meets the requirement of H.S.E. and improves the level of security of the rig effectively and reduces the frequency of security accident.

5. Appearance in red spraying plastic protection, the color enable the operator to concentrate on the warning color, that can reduce the accident rate, while the color in the atmosphere through a strong ability to help the search for the helicopter to support the project location.
